About
Gill Stephens is a pioneering figure in industrial biocatalysis, whose work bridges synthetic biology and enzyme engineering to unlock sustainable chemical processes. Her research centers on the directed evolution of oxidoreductases—enzymes capable of performing challenging redox reactions under mild conditions—with a particular focus on pentaerythritol tetranitrate (PETN) reductase. In her landmark 2010 study, which has garnered 58 citations, Stephens introduced an automated anaerobic kinetic screening platform that revolutionized the directed evolution of this enzyme. By integrating robotic handling with 96-well format purification, her team achieved near-pure enzyme recovery from site-saturated libraries, dramatically accelerating the identification of improved variants for industrial applications. This methodological breakthrough not only enhanced the efficiency of biocatalyst development but also established a scalable framework for engineering oxygen-sensitive enzymes. Stephens’ work has had lasting impact, enabling greener routes to fine chemicals and pharmaceuticals while reducing reliance on hazardous reagents. Her contributions exemplify how clever automation can transform fundamental enzymology into practical, high-throughput tools for sustainable chemistry.
